Climate change is undoubtedly one of the most pressing problems facing humanity in the 21st century. This phenomenon, caused by intensive human activity, is a complex process with global impact.

Through the burning of fossil fuels, deforestation of tropical forests and animal husbandry, humanity is increasingly influencing the climate and the average temperature of the atmosphere. Every year, human release huge amounts of greenhouse gases into the atmosphere, accelerating the process of global warming.

The current average atmospheric temperature is 0.85 degrees higher than at the end of the 19th century. The last three years have been the warmest since average temperatures began to be registered.

Scientists believe that a 2 degree increase in temperature compared to pre-industrial times would be the threshold beyond which the world's environment would begin to change in an extremely dangerous way. Therefore, the international community recognises the need to avoid it.

Most greenhouse gases are released into the environment through the production of the energy needed by humans, the demand for which is constantly increasing. Scientists unanimously agree that the only way to effectively combat climate change is to fundamentally change the way we produce energy, i.e. to switch from traditional (non-renewable) sources to renewable sources.

Renewable resources are natural resources that are created and continuously renewed by nature's natural processes. This includes solar, wind, geothermal, water and biomass resources. The production of energy from these sources does not release harmful substances into the environment that cause the greenhouse effect.

In recognition of this, the European Union has set itself the objective of reducing greenhouse gas emissions by 20% until 2020 compared to 1990 level. In the same year, 20% of the Community's energy needs should be met by renewable energy sources. These measures aim not only to meet the Paris Agreement goals but also to make Europe the greenest continent in the world.

2015 In Paris, 195 countries agreed on a new global legal regime on climate change. This agreement is seen as a major historic step towards a decarbonised economy, with ambitious long-term goals to limit global temperature rise, signalling a complete phase-out of fossil fuels, and sending a clear message to investors in the energy sector that high-emission technologies will not be viable in the long term. The Paris Agreement entered into force in 2016.
